Abstract
The invention relates to a high-voltage strip coarse-fine voltage adjusting power transformer and belongs to the technical field of transformers. According to the technical scheme, the power transformer structurally sequentially comprises an iron core, a low-voltage winding (1), a high-voltage winding (2), a coarse adjusting winding (3) and a fine adjusting winding (4). The coarse adjusting winding is serially connected to the tail end of the high-voltage winding, the fine adjusting winding is allocated through a tapping switch, when minus tapping of voltage is needed, the coarse adjusting winding is dumped to reduce resistance of the high-voltage winding, so that resistance loss is reduced correspondingly. Compared with conventional structures, load loss of minimum tapping is reduced greatly, and great power loss is saved for users. In addition the power transformer is simple and convenient to operate.
Description
Technical field
The present invention relates to a kind of power transformer of high pressure belt coarse and fine voltage regulation, belong to the transformer technology field.
Background technology
At present, in the transformer of pressure regulation on a large scale, be 132(x1.5% such as Hong Kong CLP product requirement high pressure range of regulation) kV, if adopt positive-negative voltage-regulation structure (being equivalent to 124.08 ± 12x1.5% kV), then when minimum tap (this moment, load loss was maximum), because electric current is larger, the number of turn of playing a reversed role is too much, meaningless increase too much transformer load loss.
Summary of the invention
The power transformer that the purpose of this invention is to provide a kind of high pressure belt coarse and fine voltage regulation reduces the load loss of minimum tap, solves the problems referred to above that background technology exists.
Technical scheme of the present invention is:
A kind of power transformer of high pressure belt coarse and fine voltage regulation, its structure outwards is followed successively by iron core, low pressure winding, high pressure winding, coarse adjustment winding, fine tuning winding from iron core, at high voltage winding group end serial connection coarse adjustment winding, and then by shunting switch configuration fine tuning winding, when needs minus tapping voltage, get rid of the coarse adjustment winding, reduce the resistance of high pressure winding, the corresponding resistance loss that reduced.
Beneficial effect of the present invention: by reasonably each winding being arranged, by using software for calculation electric field, magnetic field, short-circuit strength etc. are adjusted, when the user needs minus tapping voltage, just can get rid of the coarse adjustment winding, thereby reduced the resistance of high pressure winding, the corresponding resistance loss that reduced.The present invention greatly reduces the load loss of minimum tap with respect to conventional structure, for the user has saved a large amount of power consumptions, and also simple to operate, convenient operation.
Description of drawings
Fig. 1 is principle schematic of the present invention;
Among the figure: low pressure winding 1, high pressure winding 2, coarse adjustment winding 3, fine tuning winding 4.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described by embodiment.
A kind of power transformer of high pressure belt coarse and fine voltage regulation, its structure outwards is followed successively by iron core, low pressure winding 1, high pressure winding 2, coarse adjustment winding 3, fine tuning winding 4 from iron core, at high voltage winding group end serial connection coarse adjustment winding, and then by shunting switch configuration fine tuning winding, when needs minus tapping voltage, get rid of the coarse adjustment winding, reduce the resistance of high pressure winding, the corresponding resistance loss that reduced.
